CSA0603X7R473K500JT 产品概述

一、产品简介

CSA0603X7R473K500JT 为 HRE(芯声)品牌的一款贴片多层陶瓷电容(MLCC),标称容量 47nF(473),公差 ±10%(K),额定电压 50V,介质类型 X7R,封装 0603(1608 公制,约 1.6 mm × 0.8 mm)。该型号定位于通用去耦、滤波与旁路场合,兼顾体积与电气性能,适用于高密度 SMT 生产线。

二、主要性能参数

  • 容值:47 nF(47,000 pF)
  • 精度:±10%(K)
  • 额定电压:50 V DC
  • 介质:X7R(-55°C 至 +125°C,温度特性在 ±15% 范围内)
  • 封装:0603(约 1.6 × 0.8 mm)
  • 结构:多层陶瓷(MLCC),低 ESR、低 ESL,响应迅速
  • 可焊性:支持无铅回流焊(符合一般 JEDEC/IPC 回流曲线要求)

三、应用场景

  • 电源去耦与旁路:靠近 IC 电源引脚,抑制高频噪声与瞬态干扰
  • 输入输出滤波:与电感、电阻配合构成 LC/RC 滤波网络
  • 模拟信号旁路:对一般精度要求的耦合/旁路电容适用(不推荐用于高精度计时或参考)
  • 通信设备、消费电子、工业控制、车载电子(非严格车规版本下)等高密度电路板

四、设计与使用注意事项

  • 电压依赖性:X7R 型 MLCC 在直流偏压下会产生容量下降,尤其在接近额定电压时变化明显。设计中建议留有裕量,若工作电压较高应查阅厂商 DC bias 曲线并适当降额(常见做法为不超过额定电压的 50%–70%)。
  • 温度特性:X7R 在 -55°C 到 +125°C 范围内容量变化 ≤ ±15%,适合一般工业温度范围使用,但不适合对温度稳定性要求极高的应用。
  • 机械应力:0603 尺寸小,抗弯曲性较弱。焊接与剪切、装配过程中要避免过大弯曲或点压,推荐合理的焊盘设计与焊膏量,减少热机械应力。
  • 串联/并联布局:若需更高耐压或更大容量,可并联或串联组合,但要注意等效容差与电压分配问题。

五、装配与可靠性建议

  • 回流焊:推荐遵循 JEDEC J-STD-020 无铅回流曲线,最高峰值温度通常不超过 260°C;严格控制升降速与停留时间以防裂纹。
  • PCB 设计:建议使用厂商推荐的 0603 焊盘尺寸与过孔布局,确保焊点湿润良好,避免“桥接”与冷焊。
  • 贮存与搬运:干燥环境保存,长期暴露在高湿下可能影响可焊性,使用前如有必要进行回流前烘烤以去除水分。
  • 可靠性:MLCC 本身无极性、寿命长,若应用在振动与冲击环境(如车载)需结合具体机械应力评估并可考虑加固或选择更高可靠性封装。

六、包装与订购提示

CSA0603X7R473K500JT 通常以卷带(reel)方式供货,适配自动贴片机。订购时请确认包装规格(卷盘数量)、生产批次与 RoHS/REACH 等合规要求。若对温度系数、DC bias 特性或车规等级有更高要求,建议向供应商索取详细数据手册与性能曲线以便验证。

总结:CSA0603X7R473K500JT 提供在体积受限电路板上的稳定去耦与滤波能力,是常见的通用 MLCC 选择。在设计与生产中注意 DC bias、回流焊温控及机械应力管理,可确保器件发挥最佳性能与可靠性。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
